Nova Router 1.5B is the tool-routing model for Nova, the local AI assistant built into Eight.ly OS. Given a user request, it decides which NAS management tool to call (and with what arguments) across the full Eight.ly tool catalog — Docker, storage, VMs, LXC, file sharing, and system administration.

It is a fine-tune of Qwen2.5-Coder-1.5B and scores 99% tool-selection accuracy on the Eight.ly evaluation suite.

Role in Nova

Nova is router-in-front: this 1.5B model is the single tool router for every conversation. It runs as a hidden dependency — it is installed automatically alongside whichever talker (conversational model) the user chooses, and is never selected directly. The router picks the tool; the talker writes the reply.

user query → intent classifier → retrieval (nomic-embed-text) → Nova Router 1.5B (picks the tool) → talker (writes the reply)

Usage

ollama pull hf.co/smashingtags/nova-router-1.5b:Q8_0

Within Eight.ly OS this is handled automatically — installing any Nova talker pulls this router and the retrieval embedder with it.
